Hey, don't give up ! I'm 25, stuttering since I'm young, i'm having some random blocking, it goes crazy when i'm anxious/ stressed out. I had those days that I couldn't even plug 3 single words in a sentence without going crazy. My best tip I could say to you... accept it and live with it! I'm the "funny" guy in my friend group... and yes I miss alot of "one-shot joke" opportunity because of my blocking, but i'm always trying to speak and when i'm stuttering, I'm just admitting it and we all laugh together. I take the opportunity to take a deep breath and move on. Same thing with my girlfriend, she's with me and we laugh when it happens :) You just have to make the girl laugh and she wont feel sorry at all about you if you accept and deal with it ! Try to speak alone, or read a book out loud.. analyze your breathing and body behavior while you're doing it and then try to get the same behavior when speaking with someone; it helped me alot Good luck :))
